By performing altitudinal migrations involving only short horizontal distances, species from alpine grasslands of the TMVB are expected to have persisted relatively in situ, with altitude being the main variable influencing possible habitat connectivity, and thus gene flow, among mountains in the past (Toledo 1982; Graham 1999).
We here demonstrate a simple, fast, cell-free method capable of producing highly-organized, anistropic collagen fibrillar lamellae de novo which persist over relatively long-distances (tens to hundreds of microns).
However our data suggest that the overall luminosity state (brighter or darker) of a cell tends to persist over relatively long periods of hours, comparable to the doubling time.
Our results reveal that the CNB domains persist as relatively denaturation-resistant cores, a feature that might be advantageous for permitting large scale conformational changes that are of importance for the different functional states of RIα.
There are reports showing that in cells treated with trehalose, intracellular trehalose concentration can be maintained for an extended period of time [27], suggesting that effects of trehalose on the structure and functions of proteins can persist for relatively extended period.
By contrast, parasitic endosymbionts persist for relatively short periods in a given host lineage and frequently switch host species.
Long range haplotypes persist for relatively short periods of time, since, after 30,000 years random recombination events tend to break down the haplotype, leaving fragments that are too short to detect [ 12].
Efficient fascia regeneration is initiated only in certain combinations of the leg load parameters including appropriate intensity and duration time, e.g., either low density distraction that persist a relatively short time or high distraction rates.
As a result, efficient fascia regeneration is initiated only in certain combinations of the leg load parameters including appropriate intensity and duration time, e.g., either low density distraction that persist a relatively short time or high distraction rates.
In honeybees, paternal mtDNA is known to persist at relatively high levels in early stages of development [ 32], and paternal leakage resulting in heteroplasmy has been documented in Drosophila [ 33] and cicadas [ 34], indicating a pathway for the origin of heteroplasmy.
